Each case study describes the Global Polio Eradication Initiative (GPEI) has reduced the global decision-making process, the pre-introduction activities that incidence of polio by more than 99% and the number of countries were conducted, and the implementation process for each with endemic polio from 125 to 3. While this progress is immense, a country. Each case study concludes with a synthesis of the great deal of work is still required for full eradication of the disease. lessons learned during IPV introduction that can be applied to other countries. Using the lessons learned from Albania, Nigeria, There are two vaccines used to prevent polio: (1) the oral Polio and Tunisia—both their successes and their challenges— vaccine (OPV) and (2) the inactivated polio vaccine (IPV). OPV other countries have the opportunity to take advantage of the is extremely safe and effective at protecting children against strategies which were most effective and avoid common pitfalls. lifelong paralysis caused by the poliovirus. Over the past ten years, more than 10 billion doses of OPV have been given to Many of the findings from these case studies are programmatic nearly three billion children worldwide. More than 10 million and therefore applicable to not only IPV but also to the cases of polio have been prevented, and the disease has been introduction of other vaccines. reduced by more than 99%. It is the appropriate vaccine through which to achieve global polio eradication. However, OPV Albania, Nigeria, and Tunisia were selected because they are contains attenuated (weakened) polioviruses. On extremely rare geographically and economically diverse. Nigeria, is located in occasions, the use of OPV can result in paralysis due to vaccine- Africa and is eligible for financial support from Gavi, the Vaccine associated paralytic polio (VAPP) and circulating vaccine-derived Alliance. Albania is located in Europe and is an upper-middle polioviruses (cVDPVs). For this reason, the global eradication income country that was Gavi-eligible until 2013. Finally, Tunisia of polio requires the cessation of all OPV use in routine is located in the Eastern Mediterranean and is an upper-middle immunization (RI), as soon as possible after the eradication income country. Unlike Albania, Tunisia has never been Gavi- of wild poliovirus (WPV) transmission. This will leave only IPV eligible and has always self-financed all vaccine introductions. in widespread use, which eliminates the chance of VAPP cases and the circulation of cVCPVs (IPV does not cause these), By comparing and contrasting this diverse set of countries for allowing for complete eradication of all polioviruses in the world. this case study, it is possible to illustrate some of the similarities and differences between countries related to these factors. At the end of 2012, global immunization experts made a landmark recommendation that every country in the world Reasons for success seen across countries exclusively using the oral polio vaccine (OPV) should add • IPV was best accepted by caregivers in countries where there at least one dose of the inactivated polio vaccine (IPV) to was a history of public trust in the immunization program. their national immunization schedule by the end of 2015. • Strong, clear and simple messages are the most effective The primary role of introducing one dose of IPV into routine for caregivers. In some countries, the most effective immunization programs is to mitigate risks associated with messages did not specifically mention polio, IPV, or OPV. OPV withdrawal and possible reintroduction of polioviruses. The messages simply stated that a new vaccine was being introduced
